Description:

mxDateTime is an extension package that provides three new object
types - DateTime, DateTimeDelta and RelativeDateTime, which let you
store and handle date/time values in a much more natural way than by
using ticks (seconds since 01.01.1970 0:00 UTC; the encoding used by
the time module).

You can add, subtract and even multiply instances, pickle and copy
them and convert the results to strings, COM dates, ticks and some
other more esoteric values. In addition, there are several convenient
constructors and formatters at hand to greatly simplify dealing with
dates and times in real-world applications.

In addition to providing an easy-to-use Python interface the package
also exports a comfortable C API interface for other extensions to
build upon. This is especially interesting for database applications
which often have to deal with date/time values (the mxODBC package is
one example of an extension using this interface).
